The locker or like door 1, in the construction shown is of the marginally flanged plate metal type, the upper and lower flanges of which are formed with guide orifices for the upper and lower verticall arranged bolts of the present multiple be t operating mechanism.

The enclosing casing of such operating mechanism is of a plate metal formation,

in which a suitably formed blank is bent and folded to provide a flat main web or wall 2 formed with a circular orifice, reinforced in the manner hereinafter described, to provide a bearing for the journal hub of the hereinafter described operatin handle of the mechanism. At its upper an and lower edges, the web 2 carries integrally formed and angularly arranged flanges or walls 3-, with the free ends of each flange or wall formed with a subflange 3 for confining engagement with-the hereinafter described cover plate of the mechanism. In addition the flanges or walls 3 are cut away to provide guide channels for the respective upper and lower vertical bolts of the mechanism, as illustrated in Fig. 2.

At its forward side the main web or wall 2, carries a vertical flange or wall 4-inwhich is formed a guide orifice having guiding engagement with the locking tongue of the hereinafter described cam plate of the mechanism, and in the construction shown in Figs. 2 and 3, the adjacent reinforcing flange of the door 1 is formed with a guide orifice in alined relation to the guide orifice of the flange 4, with the wall 2 and its flange 4 constituting means whereby the enclosing casing of the mechanism is attached in place on the inner side of the door 1 by ordinary spot welds or other usual attaching means.

At its rearward .end the main web or wall 2 carries a vertical .flango or wall 5 the edge of which provides a uide and bearing for the rearward end of t e cam plate above referred to.

In the rearwardportion of the interior of the enclosing casing, a reinforcing member 6 of plate metal is attached to the main web or wall 2 of the casing and is formed with a circular orifice complementary to the above described circular orifice in the web or wall 2, and in the preferred construction as shown the material of said web or wall 2, and of the reinforcing late 6, adjacent to said orifices are displaced inwardly as shown to provide a receiving space for the inturned mar inal flange 1 of an orifice formed in the oor 1 in ali ed relation with the orifices just describe The described construction 15 adapted to provide an extended and substantial bearin for the journal hub of the operatin han le of the mechanism, and a like exten ed bearing in a receiving recess 7 in the margins of the aforesaid orifices of the web 2 and plate 6, into which recess 7, the hereinafter described transverse bolt of a cylinder lock mechanism is adapted to have engagement.

In the forward portion of the interior of the enclosing casing, an an lar plate metal member 8 is secured with its main web attached to the main web or wall 2 of the casing, and its flange 8' forming a bearing or support for cam plate above referred to, and at the midlength of said plate.

The operating cam late or member 9 of the bolt operating mec anism above referred to, is of a flat plate metal formation havin a latching tongue 10 at its forward end adapted to move in the aforesaid guide orifice of the flange or wall 4 of the casing and in an ali ned orifice in an adjacent marginal flange 0% the door 1, with the free end of said tongue adapted to engage in a receivin recess of the door frame of the door 1.

he proper position of the cam plate 9 during its movements is maintained by the aforesaid flanges 5 and 8' of the enclosing casin in connection with the hereinafter described coverplate of said casing and flanges 9' formed on the rear portion of the cam plate 9 and having sliding engagement on the reinforcing plate 6 as shown in Fi 1.

The cam plate 9 is also formed wit] a vertically elongated slot 11 near one corner for operative engagement with the crank pin of the operating arm hereinafter described, and with a pair of oppositely extendingcam slots 12, each of which is individual to a vertical bolt 13 of the mechanism, and to such end has operative engagement with a lateral stud 13 on the end of each upper and lower bolt 13 of the mechanism. In the preferred construction shown in Fig. 2, the inclined cam slots 12, near their adjacent ends, are formed with horizontal extensions 12' in which the aforesaid studs 13 of the bolts 13 have entry in an open condition of the mechanism and are supported against a gravitystress of the lower one of the bolts 13 to resist a tendency of said bolt to move the mechanism from a fully opened and proper position.

The upper and lower vertically arranged bolts 13, above referred to, are preferably formed with cylindrical outer portions having sliding engagement in guide orifices in the upper and lower flanges of the door 1, and with inner 'sq'uared portions havin sliding engagement in the before mentione guide passages of the enclosing casing of the bolt 0 erating mechanism, with the adjacent en s of such inner uared ortions of the bolts carrying the atoresai lateral studs 13' in o rative en agement with-the cam slots 12 o the cam plate 9. Said parts are held in operative enga ement by a sliding fit between the squared portions of the bolts 13 and the cam plate 9 and the reenforcing plate 6, as shown in Fig. 3.

The operating handle 14, is preferabl of the leveror lateral arm type shown, wit its body portion formed with a reduced 0 lindrical journal hub 15 ada ted to fit and ave turning movement in t e heretofore described aligned orifices in the door 1, web 2 and reinforcing plate 6 of the enclosing casing of the bolt operating mechanism. In the construction shown, the handle hub 15 is held from longitudinal movement by the annular shoulder 16 of the body portion of the handle 14, and at the rear end by the hub portion of the operating crank arm 17, which as shown, carries the crank pin 18 in operative engagement with the elon ated s 0t 11 of the cam plate 9 to impart reciprocation to said cam plate.

The hub portion of the crank arm 17 is fixed on the rear end of the handle hub 15 in a detachable manner and preferably by a plurality of eccentrically arranged studs 19 on the hub 15 engaging in corresponding orifices in the hub )ortion of said crank arm and held in place y one or more screws 20 as shown.

In the preferred form of the invention, the body ortion and cylindrical bearing hub 15 o the operating handle 14 are formed with an axial bore adapted to receive and house any usual and suitable type of cylinder lock mechanism, with the revoluble barrel 19' of said cylinder lock mechanism having 0 erative connection with a transversel sli ing bolt 21 moving in a guideway in t e rear end of the journal hub 15 of the handle 14 by means of an eccentrically arranged stud 16 on the inner end of the barrel 19' engaging in a cross slot formed at the mid-length of the bolt 21 as shown in Fi 4. In the described construction the sli ing bolt 21 is adapted to engage in the heretofore described marginal recess 7 of the bearing orifices in the web 2 and reinforcing plate 6 of the enclosing casing of the bolt operating mechanism, to lock the operating handle 14 and its parts against a turning movement.

The cover plate 22 heretofore referred to is formed of plate metal and is adapted to slide into place beneath the subflanges 3 of the flanges 3 of the mainweb 2 of the enclosing casing of the bolt operatin mechanism. Atits upper and lower e ges said cover plate is formed with folds 22' i which have bearing against the rearward face. of the cam plate 9 to maintain the parts in proper position in the movements of the cam plate.
